Sparkling Flashcards
Grape requirements
- low sugar
- high acid
- sufficiently ripe flavors (no green)
Why are cool regions better?
changes to sugar and acid happen slowly
Why is hand hand harvested prefered?
hand picked to retain whole bunches of unsplit grape
Why are whole bunches pressing used?
- pressing must be gentle to avoid extraction of tannins and color
- avoid crushing, contact between skins and juice is minimized
Traditional method steps
- Base: 1st ferm: dry, neutral flavored, high acid
- Blend: 3 reasons
- Liquere de tirage (mixture of wine, sugar, yeast, yeast nutrients, clarifying agent) added (second fermentation)
- Lees: autolytic character (bread, biscuit, toast)
- Riddling: hand or gyropalatte
- Disgorgement
- Liquere d’expedition/dosage (wine and/or sugar) added and corked
- Bottle aging
*bread, biscuit, toast
Why blend?
- consistency
- balance
- complexity
Liqueure de tirage
mixture of wine, sugar, yeast, yeast nutrients, clarifying agent
Yeast autolysis flavors
bread, biscuit, toast
Liquere d’expedition (dosage)
mixture of wine and sugar
Transfer method steps (“bottle fermented”)
- base wine (dry, neutral flavored, high acid)
- blending
- second fermentation (liquere de tirage added)
- yeast autolysis
- disgorged into a tank under pressure
- filtered to remove yeast lees
- liquere d’expedition added
- bottled
*bread, biscuit, toast
Tank method steps
- Base wine fermentation in temperature controlled stainless steel (no MLF or oak)
- Second fermentation in sealed tank
- Filtered to remove yeast lees
- Bottled
*no bread, biscuit, toast > retains flavors of base wine
Wines that use tank method
- Prosecco
- Muscat and Riesling sparkling wines
Asti method steps
- Chill juice
- Warm juice during partial fermentation in pressurized tank (single fermentation)
- Initially CO2 allowed to escape but then stopped
- Chilled to stop fermentation
- Filtered to remove yeast lees6. Bottled
Style of wine for each sparkling method
- traditional method: autolytic character
- transfer method: autolytic character
- tank method: retains flavors of base wine (Prosecco)
- asti method: sweet fruity, low alcohol
- carbonation method: fruity, retains flavors of base wine
Carbonation method steps
- CO2 injected into still wine
- bottled under pressure
